To all whom 15mn/,y concern Beit known that l, HAROLD G. WARR, a citizen of the United States, residing at Chicago,` in the county of Cook and Sta-te of Illinois, useful Improvement in Tie- Spacer Fuleiuins, of which the following is 'a full, clear, concise, and exact description.

My invention relates to improvements in tie spacer fulcrums.

The objects of the invention ere, to provide an improved device of this character having rounded, rail-engeging surfaces, thereby .avoiding sharp edges which' wear away in service and decreese the useful life of the device; t'o provide device which iii-sy be applied to the base of the rail es distinguished from the head, but which provides,

suilieien-tly high to ratio; te provide a nevertheless, a fulcruin give the desired leverage device devoid of local weaknesses developed in shrinking after casting' the same, and to provide a, device of generally improved design and convenience in use.

ln the accompanying drawings, l have ilustrated two structures which invention. may be devised'however.

Figure l is a top plan view of device.

Fig. 2 is a side elevation thereof.

Fig. `3 is an end elevation of a. modied form of device showing the reletion thereof to the rail, cross-tie and crow-her.

A flat transverse portion@ against the baseof the rail and has a pair or vertical curved walls 4, 5 projecting upwardly therefrom, between which the rail case is received. The well i is provided with en overhanging` lip or'llenge forming loosely over 'the rail base, the angle of the j ew being somewhat greater than the angle of the corresponding section of the rail bese to L ermit device to tilt somewhat in applying it to fl i remainder of the device have invented a certain new and Other forms of thev invention ,ally and upwardly and is desi ally by reference 7.

corners. In certain prior devices, the skewingof the tie spacci' tnlcruin results in the rail being gripped between a p aii of corners which in course ot' time wear away, thereby causing the device to skew at an increasing angle, and eventually causing it to be discarded.v `With the present construction, the wear is very gradual and is distributed s that the useful lite of the device is niaterially increased.

In 'using the device as a fulcrum, it operates equally well regardless of which side thel pressure is applied to; that is to say, it gripslthe rail equally well whether skewed en the rail in one direction or the other.l In the first forni of device, two tulcruin siiriaces are provided whereby a tie may be moved either wayy by appll ing the lever to either side of the .fulcruiii structure. In the second form et' device, only a single surface is provided.

Diliiculty has also been experienced heretofore where the tie spacer iilcruiii has been made of' cast metal, in that the device would crack or break at or near the middle, when a powerful leverage was applied to it. he thickness ot' the metal necessitated by the great bending moment. applied to this point,

resulted in strains developed by shrinking of the inetalafter casting it', as a result et' which local weakness developed, causingtlie ln the present case, this disadvantage is obviated b v the proportioning' of parts disclosed, wherein the metal is ot' substantially uniform thickness at all points, and at thevsaine -tinie the vertical depth of the'flanges is ample to withstandI to the head of the rail, but such practice is objected to bythe railroads. I n the present device, the fulerums are. at 'a considerable elevation above the top of the tie, whereby the desired leverage ratio is obtained.

lWhen the device is. applied to rails of different sizes, there is not only a variation in the amount of skewing as previously stated,

ut the variation in the vertical thickness of the rail flanges 'at the sides of the rail ln a vertical plane. In Fig. 2 where thet rail may be assumed to. be of inaxiinniirA thickness in its flanges, the transverse ele-- ment 3 is horizontal, but if the rail were of' less thickness, said element would incline downwardly to the left somewhat, providing a clearance beneath the left hand side oi the rail base, since the device is supported on the rail at the point l0.

Various changes `may be made in the structures illustrated Without departing from the Spirit of the invention.

TWhat I claim as new and desire to secure .by Letters Patent ot the United States is:- l. A device of the class described, coinprising a transverse element having-a pair ot.' vertical curv'ed walls thereon arranged to receive the base of a rail between them and an extension thereon adapted to project te one side of the rail, said extension providing a' fulcruin.

2. A device of the class described, coinprising a casting having means for supporting it on the fiange of a rail and being providedv with deep reinforcing iianges on its under side, said Ganges tapering toward opposite ends et' said casting, the taper at one end being less than at the other end to make one hait' of the casting heavier than theI other, said heavier portion being adapted to extend to one sidev of the rail base to keep the device in operative position thereon.

.ln witness whereof, I, hereunto subscribe my naine this 29th day of December, A. D.
